The average concentration of Carbon Monoxide in a city's air in 2006 was 4.5 ppm. The average atmospheric pressure of the city is 754 Torr. (a) Calculate the partial pressure of CO. (b) Calculate the number of CO molecules in 1.0L of this air at a temperature of 25°C
The concentration of carbon monoxide in a trench is found to be 0.037 g/m3 a. What is this concentration in mg/m3 ? b. How does this concentration compare to the TLV of 25 ppm, assuming an ambient temperature of 77°F (25°C) and pressure of 760 torr (760 mm Hg). c. What would the concentration (ppm) be at an ambient temperature of 32°F (0°C) and pressure of 760 torr (760 mm Hg).
QUESTION 12 The concentration of carbon monoxide (CO) in cigarette smoke reaches 400 ppm. For this particular value determine the concentration in milligrams per cubic meters, at 25 0c and 1 atm. 0 4.57 mg/m O 457 mg/m3 O 4057 mg/m3 45.7 mg/m3
One hour carbon monoxide concentrations in the air samples from a large city average 13 ppm with a standard deviation of 9 ppm. Assume that the carbon monoxide concentrations are normally distributed. Seattle Washington wants to improve the city's carbon footprint by the year 2020. Based off the national results, what does Seattle's carbon monoxide concentration need to be if they want to be in the bottom 10%?
1b. In some countries, the limit for the average concentration of carbon monoxide (CO) in an 8-hour period is set at 9 ppm. Express this amount as a percentage.
There is an average concentration of ethane of 2.51 ppb in the atmosphere. If the air temperature is 21.7°C and atmospheric pressure is 0.987 atm, express this concentration in units of a) ppm b) atm c) molecules/cm3 d) μg/m3 e) Determine the total mass of ethane in the atmosphere in grams with an appropriate prefix
Exhaust gas emitted by a particular automobile contains 20 g of carbon monoxide (CO) for every km driven. If this car is driven 30 km, how much carbon monoxide will have been emitted, and what would be the volume of the carbon monoxide after it cools to 25°C at a pressure of 1 atm? Assume carbon monoxide (and the atmosphere) acts as an ideal gas. Per km of travel, what volume of air could be polluted by the carbon monoxide...
Recently, I measured the carbon monoxide (CO) mixing ratio out on the street in front of An-Najah as 42 ppm (during "rush" hour). If the ambient temperature and pressure were 22.3°C and 700.7mmHg: 1) What is the equivalent concentration in ug/m3? 2)Assuming my lungs absorbed all of the CO I inhaled (~6 Lpm) during the 60 minutes I was out there, what total mass of CO was in my blood stream?
